    Abstract: An image forming apparatus has a power-saving mode in which the image forming apparatus is switched from a normal power consumption state to a low power consumption state where less energy is supplied than in the normal power consumption state. This image forming apparatus includes a detection unit configured to detect an operating state of the image forming apparatus, and a memory unit configured to store a detection result by the detection unit. In the power-saving mode, the detection unit detects an operating state of the image forming apparatus, and the memory unit stores a detection result by the detection unit. When the image forming apparatus returns from the low power consumption state in the power-saving mode to the normal power consumption state, control of a return operation for the image forming apparatus from the power-saving mode is executed, based on the detection result by the detection unit stored in the memory unit.

    Abstract: Image descriptions described using an image description language are provided for a plurality of images. Image bitmaps are determined by processing the image descriptions, each image bitmap including an array of image pixels. The image bitmaps are stored in an array of digital storage devices, with different portions of the image bitmaps being stored in different digital storage devices, where an allocation table is used to indicate where each portion is stored. When one of the digital storage devices fails, the allocation table is analyzed to determine which portions of the image bitmaps were stored in the failed digital storage device. The lost portions are re-rendered by processing corresponding portions of the image descriptions, and the re-rendered portions are stored in the array of digital storage devices.

    Abstract: Systems and methods for identifying problematic printers are provided. An example method can involve determining a time interval for a printing device. The method may also involve determining a number of pages printed by the printing device during the time interval. The method may also involve determining a number of printing-device errors that occur on the printing device during the time interval. Still further, the method may involve determining one or more coefficients of a Markov chain based on the number of pages printed by the printing device during the time interval and the number of printing-device errors that occur on the printing device during the time interval. The method yet further includes, based on the determined coefficients of the Markov chain, determining an operational status of the printing device.

    Abstract: A method and a system for reducing update frequency of an image processor, in particular a software and/or a component. The image processor enables modifying the quality of digital images derived from and addressed to a set of appliances. The set of appliances includes an image capture device and/or an image scanning device. The image processor uses formatted data dependent on at least one variable, associated with defects of at least one appliance of the set of appliances. The formatted data includes parameters of at least a parameterable model dependent on the variables. The formatted data enables establishing a correspondence, in particular by a correspondence table, between part of the variables and identifiers. The identifiers enable determining the value of the variable corresponding to an identifier taking into account the identifier and the image.
